A magnetorheological (MR) damper is a type of smart device that utilizes magnetorheological fluids—fluids whose viscosity can be altered by an applied magnetic field. A simple design is provided by a Magnetorheological (MR) damper, which consists of MR fluid, magnetic coils, and a hydraulic cylinder. In addition to being easy to construct and controllable in the field, MR dampers have several other benefits, including a relatively low power input need, the capacity to generate high yield stress up to 100 kPa, and stable operation over a broad temperature range (-40ºC to 150ºC). while MR silencers are designed to function between -40ºC and 150°C, their effectiveness in specific scenarios may be influenced by additional factors beyond the operational limits of the MR fluid alone. MR fluids are also non-toxic and impervious to contaminants. The MR damper can operate as a traditional passive dashpot in fail-safe mode when there is no magnetic field. Due to these advantages, MR dampers are becoming increasingly popular in a variety of applications, such as knee prosthesis, big bridge vibration control, automotive suspensions, and seismic vibration mitigation. The performance of the developed damper is compared to a standard MR damper to determine the optimal blend for vibration attenuation Understanding the nonlinear hysteretic behavior of an MR damper is essential for effective control under an applied magnetic field. In present work Magnetorheological damper is designed, built, and tested for piping vibration having load carrying capacity of 1910N and its transmissibility for various blends of MR fluid with percentage 40% , 45% and 50% (by weight of oil in damper) is observed and corresponding transmissibility of damper is compared with Standard Magnetorheological damper
